Volcanic rock media

The surface is rough and has many micro holes, these characteristics are suitable for the micro biological animals to grow and breed, which can be shaped in to a film. Owing to the volcanic filter, the volcanic filter pond could not only treat the civil contaminated water, but also biological industrial waste water, living drainage water and lightly contaminated water.

In the water treatment, it can also replace quartz sand, activated carbon, anthracite and so on which can be used as filter medium. Meantime, it can do the deep treatment for the behind water which has been treated on second level by the waste water treating factory. If the treated water exceeds to the reused water’s standard, then it can be reused as middle water.
